imagemagick: fix bogus rpath in perl .so files

The perl binding .so files are being built with RPATH prefixed with
the build's work directory because the imagemagick libs aren't
installed yet. Rebuild the perl binding with LD_RUN_PATH removed
from the linker command line.

Also, change '--with-lcms=no --with-lcms2=yes' to '--with-lcms=yes'.
Upstream changed the lcms flags again. Seems only lcms2 is actually
supported and --with-lcms is the only current switch for that now.
